Liwaco made some neat LCD games that have a tiny LCD screen that you move to
assist in the game play (See The Ninja and Iron Boy). Their games were manufactured
by Morioka Tokei Co. of Japan. Morioka Tokei is still a huge watch movement
manufacturer. Quite a few inexpensive analog watches use their movements (Armitron
and others...). A lot of these games were also sold in Japan under the name
Yonezawa.
